Abstract

PURPOSE:To obtain a new heptapeptide useful for living body-related complex adhesive, surface coating material, etc., in medical, dental and veterinary fields as a bioadhesive, having a specific amino acid sequence, similarity to adherent protein of hard-shelled mussel produced in Chile and excellent biocompatibility. CONSTITUTION:The compound shown by the formula HCL.H-Gly-OMe (Me is ethyl) is bonded to the compound shown by the formula Boc-Ala (Boc is t-butyloxycarbonyl) in the presence of a condensation agent to give the compound shown by the formula, Boc-Ala-Gly-OMe. Similarly the compound shown by the formula Boc-Tyr(Bzl)-Gly-OMe (Bzl is benzyl) is synthesized and these compounds are bonded to give the compound shown by the formula, Boc-Ala- Gly-Tyr(Bzl)-Gly-OMe. Then, this compound is saponified, condensed with the compound shown by the formula Boc-Gly-X-Lys(Z<2>Cl)-ONp (X is Ala, Val, Leu, Ile or Phe; X<2>Cl is amino-protecting group; Np is p-nitrophenyl) and deprotected to give the objective heptapeptide shown by the formula.

Recently, a method for purifying the adhesion protein of Chilean mussels has been reported. This repeated heptapeptide-based adhesion protein is a repeat peptide chain that is shorter than the repeated decapeptide-based protein of the Mussel snail, so it is promising as a far cheaper bioadhesive than the Murakiki snail. However, the sample is supplied exclusively from the purification of natural products.

Gly-X-Lys) n and X at the 6-position is a hydrophobic amino acid (Ala, Val, Leu, Ile, Phe). Generally, peptide synthesis incorporating Dopa is considerably difficult, and if Dopa can be read as Tyr, the degree of difficulty is reduced. INDUSTRIAL APPLICABILITY The peptide of the present invention can be insolubilized rapidly and simply in water and can have adhesiveness, and is used as, for example, a biocompatible adhesive. Specific applications include biomedical composite adhesives in medicine (internal medicine, surgery, ophthalmology), pharmacy, dentistry, and veterinary medicine.
